I was dating a boy, named Li, for about four years. But, just a year ago, his mother moved his family back to China to pay for treatments of Leukemia for his little sister Xhou...she was really sick. But, just about a week ago, his little sister Xhou gave me a call, telling me that she had something to say, and that she had just found out that Li had been dating another girl...one of the few public concubines left in China. But, he was the one who told me he wanted to stay together...and then cheated on me, and I had just turned down a date with the perfect guy...and by the time I knew I was single again...he had found another girlfriend...and Li made me miss out on something great, but I still love him...and it makes me sad. Is this fair for me? Or, am I just over-reacting?
